HOSE-COUPLING.

Specification of Letters Patent No. 31,108, dated January 15, 1861.

To all whom it 'may concern:

Be it known that I, AMBROSE E. BARNARD, of Paterson, Passaic county, State of New Jersey, have invented, made, and a )plied to use a new and Improved Coupling for Hose; and I do declare the following to be a full, clear, and correct description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in whichh Figure I is a. front view of coupling; Fig. II, a vertical cut section of the same; Fig. III, a top view of the same; Fig. IV, a top View of cast india-rubber ring employed; Fig. V, a cut section of cast india-rubber ring employed; Fig. VI, a top view of claspring employed; Fig. VII, a view of wrench employed in detaching coupling.

In the drawings, like parts of the invention are designated by similar letters of reference.

The nature of the invention consists in the construction and operation of a coupling for hose as hereinafter set fo-rth.

To enable those skilled in the art to make and use my invention, I will speak of its construction and operation.

A shows a butt provided with an L flanch a? about midway of its length; said L tlanch forming a cup into which the indiarubber ring C is inserted. This ring C is slipped over the upper end of the butt A, and contracts into the groove a, in the butt A, turned out to receive it, thus allowing the edge of shank of ring C to contract within the surface of the said butt A, so that the cap or head B when thebutt A is inserted, will not strike the edge of the ring C, but will have a snug bearin upon the shank C of said ring.y The sai india-rubber ring C, which is of a square form, is cast or pressed into `the shape required in a mold constructed for the purpose, said mold being so constructed as to form a circular groove or recess in its interior, open from the top, said groove or recess forming the lip c and the vertical tapering shank c as shown in cut section Fig. V. At the same time, the shoulder of the head or cap B ,having a bevel groove turned into its under surface, in pressing upon the outer edge of the ring .C compresses and tips the lip c up into the bevel groove aforesaid.

rlhe cap or head B is held firmly in position by the spring-catches D, let into and firmly secured to the lower end of the butt A. These spring-catches D D are compressed and held in position by the clamp ring E, said ring E being kept in position by pin l on one of the catches D, the said ring E having a vertical groove cut into it, to allow the same to pass freely over the said pin d, andupon turning the ring E sliglhtly, has a bearing upon thepin CZ aforesait.

Insert the butt A into the cap or head B; press the cap or head B down upon the ring or washer C, until the spring-catches D D, clasp over the edge of the shoulder b of the said clasp B. Bring up the ring E and pass the same over the pin Z and turn the said ring E to the right, when it will be retained in its position by said pin d and prevent the spring-catches D D from being forced from their grip upon the shoulder b of cap or head B aforesaid. ,To detach the coupling, return the ring E until the groove c comes over the pin d; drop the said ring E thereby releasing the spring catches D D; insert the forked wrench, shown in Fig. VII, between the said catches D D and the butt A. In pressing it, (the said wrench) the forks of which are made tapering, the spring catches D D are forced back and the cap or head B is released and easily removed.

Advantages.

First, the expeditious manner in which lengths of hose can be readily attached and detached, which is of essential importance in case of a lire.

Secondly, the employment of an india rubber ring made in the manner set. forth, forming a self-acting washer. In the first place the cap or head B being pressed down upon the shank c of ring C as described, forms a comparatively tight joint, but if, under great pressure, the water should be forced through into the groove of said ring, the pressure forces the thin edge of lip c, of the ring C, firmly up into the bevel groove of the ring C, firmly up into the bevel groove of the shoulder b of the cap B and thereby makes it a perfectly tight joint.

Third, the simplicity of a coupling, formed in this manner, its non-liability to get out of order like the coupling now in use, while it can be made as strong and 2 i 31,103 f q compact as required, and by its employment 2. In combination with the same, the butt lo all screwing together of the butts is dis- A, cap B, spring catches D D and clamppensed with. ring E arranged and operated as set forth Having thus described my invention, what and for the purpose described. 5 I cla-im as new and desire to secure by Letters Patent is, A' E' BRNARD l. The india-rubber ring C made in the In presence ofmanner described, which constitutes an GEO. I). GORDON, automatic or self-acting Washer. J. W. BECKWITH.
